一种基于smith预估器的温控系统
摘要:随着生产过程控制要求的不断提高以及控制理论与控制技术的不断发展和进步,自动化工作者不断开发出许多适应新的生产形势的控制系统。这里把他们归结为一类,称之为新型控制系统。Smith 预测控制就是其中一种,它能有效的解决控制系统中控制通道的纯滞后问题,减少超调量并加速调节过程。
针对电加热炉温度控制系统的大时滞问题,提出了一种Smith预佑控制器的设计方法,并由8086微机系统实现。认为该方法能有效克服大纯滞后对控制系统稳定性的影响。计算机仿真与实验研究表明,其控制效果明显优于常规PID控制,非常适用于电加热炉的温度控制。
关键词:Smith预佑器温度控制微机电热炉
毕业设计(论文)外文摘要
A kind of temperature control system based on Smith predict
Abstract: Along with the unceasing development of the unceasing raising of production course as well as control theoretical and control technology, automation worker development a lot of control systems that meet new production situation. we call them a kind of new control system. It is in which a kind of that Smith predict, it can be effective to solve the pure
hysteresis problem of control passageway in control system, decreases the exceed tunequantity and accelerate regulation course.
Aiming at the large delay in temperature control system of Resistance stove,
Puts forwards A design mith predicting controller, realized by an 8086 puter system. Holds that by this way the influence of the large pure delay on the system stability can be e. Computer simulation and experiment research show that it is very suitable for temperature control of heat exchangers with better effects than conventional PID control.
Keywords: Smith predict;temperature control; puter;Electrothermal stove .
